is water in liquid form below minus four degree centigrade at normal pressure ?

Question

how the fish are alive in a frozen lake ?

Answer 1

Water can be liquid at -3.98 degrees but it is too dense to differentiate from solid.

Fresh water has it's liquid form from -3.98 to 99.39 Degrees C

The above facts are about fresh water.


In a frozen lake, the topmost layer is frozen and it acts as an insulator for heat at bottom to get away to the atmosphere. The bottom is generally at 4 degrees.
Fishes can survive upto 2 degrees and hence, they can be alive in a frozen lake.

Answer 2

Water is liquid at -4 degree centigrade, marine life survive below the frozen lake because the temperature at the base of lake is +4 degree centigrade .

Answer 3

4 Degrees Centigrade

Answer 4

I don`t think that it is possible that water remains liquid at -4C. And about fishes, they can survive at very low temperatures. The frozen water on the pond surface acts as a layer which prevents the water beneath from freezing & the fishes are able to survive as they have water available.

Answer 5

no.. water solidifies at 0 C.. in frozen lakes, the ice layer rises above and floats in the liquid water below, due to its low density. This ice layer does not allow the liquid water to come in contact with the atmosphere and so it does not freeze. and hence, the marine life survive in low temperatures...

Answer 6

Nope.
The temp of water under the ice layer has to be in or above the triple point of water that is 0 degrees Celsius.
That water is isolated from the cold air by the very layer of ice.

Answer 7

below - is not liquid. but under the lake warm water there and cold ice will be on topof the water

Answer 8

hrushi is right ......
